That sounds like a fascinating rabbit hole—Victorian tech was all about harnessing nature, after all, and they did leave some pretty elaborate hydraulic and wind‑powered systems hidden in those gardens. If you can map out their mechanics and see where the old steam‑driven pumps and wind‑turbines could be re‑imagined with modern sustainable materials, you might uncover a new way to power irrigation or even generate micro‑electricity. Just be sure to document every component before you start swapping gears; history doesn’t usually give up its secrets to the impatient. But hey, if you’re determined, you’ll find a lot more than just a dusty blueprint—you’ll probably discover a whole new language of green engineering.
